"It's not your fault," Natasha said, resisting the urge to reach over the table and take the napkin out of his hands. She knew that he was uncomfortable, it was written all over his face, etched into every mannerism and for a while he wasn't like that around her. For a while, she had been one of the few people that he hadn't been too nervous around. Of course, that had been before everything. So much had changed, and even Bruce had changed. He was different. She could see it.
She tilted her head, "Not yourself? The Hulk?" she asked, "For how long? What happened to you?" They could have used his help but she supposed the airport fight would have been significantly more destructive if Hulk had been around and... She'd worked a bit with the Big Guy and she knew he didn't like inter-team conflict so he wouldn't have been all that useful if they were fighting each other. She had no idea which side of the coin Bruce would have fallen, but it was likely he would have sided with Tony at first.
She wet her lower lip and pushed the plate with the lemon muffin into the middle of the table, cutting it in half easily and indicating that Bruce should help himself.
"It's good to have you back," she told him. "I'm glad."
